I enrolled for the O'Reilly class on Processing and Arduino and it starts in 30 minutes. I am hoping that it becomes useful. I do like controlP5 as a library for guis.
In the meantime I did a few utils. I have an easy save mechanism thanks to saveFrame() in Processing. I also have some sketch code for recording video. Surely this will change over the month but these are things that I thought would be important to start.
I think I may also start a template sketch so I can get straight to my idea. I'll be sure to put it up if I get to it.
